How Mobile Network Transform from 1G Analog to 5G Next Generation of Wireless Broadband?

“G” stands for generation. Each generation is superior to other. When first generation was developed it’s providing a digital network until the second next generation developed. It was a great jump to wireless network from digital network. After this 3G promised to give up to 2 Mbps speed. As 4G and above this are promising to give speed of 1 GPS (Giga bits per second) transfer rate to their user.

Now we can see below how “Standards of G” changing Mobile Communications Market after 1980.

1G = Analog

The mobile phones were first developed in the 1940s but it was not until the mid 1980s that they became widely available. In this era phone calls were developed which are connected through wires until the second generation was developed. Although, The world’s first mobile phone call demonstrated by John F. Mitchell and Martin Cooper of Motorola in 1973.The major difference in between first generation and second generation was radio signals. In first generation, it was analog while in second generation it was digital.

2G = Digital and Voice

In the second generation of cell phone transmission, a few more features were added to the menu such as simple text messaging. In this generation, cellular signals were digital. During the phone call and messages, radio signals were encrypted into digital through wires.

Examples include GSM, D-AMPS, PDC

Those could do data but only as analog modem (using the whole channel) at 9.6Kbps

3G = Digital, Supported data, but still Circuit Switched

In this generation, most of the wireless technology we came to know and loved like web browsing, email, video downloading, picture sharing chatting, video calling and other Smartphone technology were introduced. 3G should be capable of handling around 2 Megabits per second.

UMTS / WCDMA, EvDO

Includes data but still onto circuit switched architecture

3.5G faster data, added true always-on / packet data (HSPA)

Data rates of 2Mbps-tens of Mbps

4G = Wireless Broadband

The speed and standards of this technology of wireless needs to be at least 100 Megabits per second and up to 1 Gigabit per second to pass as 4G. It also needs to share the network resources to support more simultaneous connections on the cell. As it develops, 4G could surpass the speed of the average wireless broadband home Internet connection. Few devices were capable of the full throttle when the technology was first released. Coverage of true 4G was limited to large metropolitan areas. Outside of the covered areas, 4G phones regressed to the 3G standards.

4.5G term not widely used but some people say that is LTE-A

Data rates of Tens of Mbps – Hundreds of Mbps

5G = Next generation of Wireless Broadband

5G is planning to aim at higher capacity than current 4G, allowing a higher density of mobile broadband users, and supporting device-to-device, ultra reliable, and massive machine communications. 5G research and development also aims at lower latency than 4G equipment and lower battery consumption, for better implementation of the Internet of things.

In 5G an initial chip design by Qualcomm in October 2016.

The Snapdragon X50 5G modem, supports operations in the 28 GHz band, also known as millimeter wave (mmW) spectrum.

With 800 MHz bandwidth support, it is designed to support peak download speeds of up to 35.46 gigabits per second.

The following requirements that a 5G standard should fulfill:

Data rates of tens of megabits per second for tens of thousands of users.

Data rates of 100 megabits per second for metropolitan areas and 1 Gb per second simultaneously to many workers on the same office floor.

Coverage improved and Signaling efficiency enhanced.

Latency reduced significantly compared to LTE.

“Many mobile companies are planning to come with the 5G like Nokia, Samsung and Apple. These companies have launched mobile which are compatible with fifth generation. Nokia 5G FIRST allows operators to address the near-infinite capacity demands of new applications anywhere – seamlessly and securely.

On the other hand, Samsung also announced 5G mobile network products and solutions in coming time. These devices for fixed wireless access connectivity and a 5G Radio Base and core network infrastructure, among others. Samsung also has expanded its tablet portfolio with Galaxy Tab S3 and Galaxy Book.

Nice Article
Today, i have seen the news regarding the launch of Nokia Smartphone. Nokia 3, 5& 6. All these three have 4G LTE Support. they were talking about 5G network but recently launched 4G LTE only.

Typically I would not master write-up for information sites, nevertheless i wish to declare that this specific write-up very pushed me you need to do hence! A person’s way with words continues to be stunned us. Appreciate it, extremely fantastic content.. colour blindness facts
